'HAY-STACKER AND DERRICK.

SPECIFIGATIQN forming part of Letters Patent No. 688,091, dated December 3, 1901.

Application filed May 9, 1901. Serial No. 59,386. (No model.)

To all whom, it may concern.-

Be it known that I, MARV N OARLEroN HUTCHINGS, a citizen of the United States, and a resident of Bozeman, in the county of Gallatin and State of Montana, have invented a new and Improved Hay-Stacker and Derrick, of which the following is a full, clear, and exact description.

The purpose of theinvention is to improve upon the construction of hay-stackers and derricks for which Letters Patent were granted to me March 26, 1901, No. 670,674, the improvement beingsuch that one guy-rope connected with the derrick has a roller-support adjustable with reference to the ground to regulate the throw of the derrick and to provide the said guy rope with an attached weight which will return the derrick to its normal position after a load has been discharged.

Another feature of the invention is to provide a brake for the weighted guy-rope which may be quickly brought into action by the person handling the load to prevent the toorapid inclination of the derrick and to hold the derrick from inclining beyond a certain extent when desired.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the improvement applied to a derrick. Fig. 2 is a bottom plan view of that portion of the improvement at which the derrick is located and through which the weighted guy-rope passes,and Fig. 3 is a side elevation of a slightly-modified form of the improvement.

Arepresents aderrick of any suitable or approved construction and which may be rigged with the usual apparatus for raising or lowering a load-a hay-fork or the like. A guyrope B is attached to one side of the derrick, and this guy-rope B is secured to a support at its lower end in such manner that the said guy-rope B may be quickly freed from the support and slackened. At the opposite side of the derrick a second guy-rope O is secured, both of the said guy-ropes B and 0 being attached to the upper portion of the derrick, and the upper portions of both guy-ropes are bifurcated, as is shown in Fig. 1. The guyrope G is provided at its lower end with a weight 10, sufficiently heavy to draw the derrick back to its normal position should it be inclined in a direction opposite to the guyrope O by the weight of the load being lifted or by other means, the said weight serving to bring the derrick back, as stated, when the load has been discharged. Thisweighted guy-rope O passes over a friction-roller 11, located in a slot 12, formed in the head portion 13 of an anchorage-arm D. This anchoragearm is provided with a tail-plate 14 at its lower end, having an opening 15 therein, through which a pin 16 may be passed into the ground to hold the anchorage-arm in position, yet in such manner that it is movable to and from the surface of the ground. The anchorage-arm D is supported by connected legs 17, and these legs are held to turn at their connecting member in a socket 18, formed at the bottom portion of a sleeve 19, which is adj ustably mounted on the body portion of the anchorage-arm, so that the anchorage-arm may be carried to or from the ground in order to give the weight 10 more or less drop, according to whether the derrick is to be allowed more or less lateral movement, and the sleeve 19 is secured in position on the anchorage-arm by a pin 20,

passed through the sleeve and into any one of a series of apertures 21 in the anchoragearm, as is clearly shown in Fig. 1.

It is frequently desirable to check the movement of the weighted guy-rope C, and to that end a brake is employed. This brake is preferably constructed as shown in Fig. 2, and consists of a plate 22, which is held to slide in guides 23 at the bottom of the head 13 of the anchorage-arm, and this plate 22 is provided with an opening 24 practically corresponding to the opening 2 in the head 13 of the anchorage-arm D, and at the rear end of this opening 24 a brake-tongue 25 is formed, which extends forwardly and is provided with a concaved forward end 26, adapted to engage with the guy-rope which passes over the roller 11, and this roller 11 has a central peripheral groove, so that the guy-rope will not slip on the roller, but will be always in position to be engaged by the brake 25. The plate 22 is connected with the body portion of the anchorage-arm l) by a spring 27, which spring serves to draw the plate to its normal position after it has been carried to an engagement with the guy-rope G. The brake is operated through the medium of a rope 28, attached to the forward end of the plate 22, which rope is passed through rings 29, supported by the weighted guy-rope O, and at the upper end of the brake-rope 28 said rope drops downward and terminates in a handle 30, which hangs over the load of hay being stacked and within easy reach of the person handling the hay-fork. Thus it will be observed that the brake may be brought into action Whenever it is required, and the main object of this brake is to check the derrick from tilting to the stack too soon, and thereby delivering the fork of hay too quickly. The brake may also be used to control the rapidity of the movement of the derrick to or from the stack.

In Fig. 3 I have illustrated a slight modification, in which the improvement is shown adapted to derricks A, used for raising stone or other material in the construction of a wall E or other portion of a building. The derrick A and the derrick A are both of them mounted to swing on a suitable base to and from the place where the material is to be delivered. Under the construction shown in Fig. 3 the guy-rope B is attached to the uppulley 31, attached to a fixed post 32 or other support, and from the said pulley the guyrope G is carried into the structure being built and is detachably secured to a support therein, so that by slackening the guy-rope O the derrick may lean over in direction of the structure, permitting the burden carried thereby to be properly directed to place; and after the burden carried by the derrick has been discharged the derrick is quickly returned to its normal position bydrawing upon the inner end of the said guy-rope 0.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. Aderrickcapableofswingingmovement, a weighted guy-rope attached to said derrick, an anchorage-arm, a support for the anchorage-arm, and a brake carried by the anchor.- age-arm and adapted to act upon the weighted guy-rope, for the purpose described.

2. A derrick mounted for swinging movement, an anchorage-arm provided with a sloteaoei ted head having a guide-roller therein, an adjustable support for the anchorage-arm intermediate of its ends, a guy-rope passed from the derrick through the slot in the anchoragearm, a weight at the lower end of the said guy-rope, and a brake carried by the head of the anchorage-arm, arranged for engagement with that portion of the guy-rope which passes through the head-section of the said arm, as described.

3. The combination,with a derrick mounted for swinging movement, an anchorage-arm, means for pivotally attaching the anchoragearm to a support, the said anchorage-arm being provided with a slotted head-section and a roller in the slot of the head-section, and an adjustable support for the intermediate portion of the anchorage-arm, of a guyrope attached to the derrick, which rope is passed through the slot in the head of the anchorage-arm to an engagement with the said roller, a weight secured to the lower end of the guy-rope, a spring-controlled brake mounted on the head of the anchorage-arm, having movement to and from the said roller and adapted for engagement with the said guy-rope,and an operating-rope for the brake, which operating-rope extends to a point near the derrick, for the purpose set forth.

4. The combination, with a derrick, an anchorage-arm provided with a slotted head at one end, a roller in said head and an apertured tail-plate at the opposite end, a sleeve adjustable upon the body portion of the anchorage-arm,- and legs pivoted upon the said sleeve, of a guy-rope attached to the derrick and passed through the slot in the head of the anchorage-arm over the roller in the said slot, a weight at the lower end of the said guy-rope, a brake-plate having spring-controlled sliding movement at the bottom of the head of the anchorage-arm, the said plate having a longitudinal slot therein and a brake-tongue at the lower or rear end of the said slot, and a cable connected with said plate, having guided movement on the guyrope, which cable extends to a point near the derrick, for the purpose described.

5. An apparatus of the kind described, comprising a swinging derrick, a head provided with a revoluble member, a rope secured to said derrick and engaging said revoluble member, and a brake for pressing said rope against said revoluble member.
